Title: Radio directing method and system
IPC: G01S1/24
Filed: 1944-04-28
Abstract: 618,497. Radio-navigation. STANDARD TELEPHONES & CABLES, Ltd. (International Standard Electric Corporation). April 28, 1944, No. 8063. [Class 40 (vii)] The course position of a craft 1, Fig. 1, is determined by receiving pulses transmitted from the craft on two spaced receivers 2, 3 and comparing the relative timing of the received pulses to determine upon which hyperbolic curve a ... e the craft lies. In a modification, the range of the craft from one of the spaced receiving stations may be determined by radiolocation means, the transmitter and receiver on the craft acting as a repeater to send back interrogating pulses, so that the position of the craft may be determined and signalled back to it. The craft carries pulse transmitter 20 and receiver 21, Fig. 2, normally provided for timemodulated pulse communication, of the type described in Specifications 511,222, 523,575 and 529,648, and by means of the communication channel requests station 3 for course information and then causes transmitter 20 to emit a train of pulses. 'Stations 2 and 3, preferably spaced by at least 25 wavelengths, comprise pulse receivers 25 and 26, the pulses from receiver 25 being fed over line 41 preferably at an intermediate frequency, to station 3 where they are fed through a variable delay network 27 to receiver 26. Receiver 26 feeds both trains of received pulses to apparatus of the type described in Specification 590,460 which selects various harmonic components of the combined pulse wave, converts them to direct currents and enables differential outputs to be observed on meters. Zero outputs indicate that a preferred time interval equal to T/4, where T equals the pulse repetition period, exists between pulses of the two received trains, and the adjustment of delay device 27 to cause zero indications to be obtained defines the course line occupied by the craft. This information is then transmitted to the craft over the communication channel from transmitter 28. To enable range to be determined, a switch 23 on the craft is closed connecting a repeater device 22 between the receiver 21 and transmitter 20. A radio distance measuring equipment 29, of the type described, for example, in Specifications 582,753 and 592,393, located at station 3, emits pulses which are repeated back from the craft to apparatus 29, the distance of the craft being determined in the normal manner.

Abstract: 1504313 Inverting NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP 5 March 1975 [11 March 1974 3 Feb 1975] 9131/75 Heading H2F A controlling system for controlling a single or polyphase bridge inverter comprises means to provide four pulse trains for the respective switching elements of the inverter, the pulse trains being anti-phased square waves X<SP>1</SP>, #X<SP>1</SP> of the required inverter output frequency and modulated trains Y<SP>1</SP>, #Y<SP>1</SP> (Fig. 3). The part of train Y<SP>1</SP>, #Y<SP>1</SP> corresponding to each half cycle of the required inverter output consists of an even number of time sections each having one pulse at its mid point, the width of said pulses in each half cycle being wider sequentially as they approach the centre of the half cycle so as to simulate a sine wave in the output of the inverter. It is shown that if the ratios # 1  : # 2  : # 3  = 0À268 : 0À732 : 1, then the third, fifth and seventh harmonies are negligible. As described, pulse source A provides a frequency 12 times the required output frequency while source B provides an even high frequency synchronized to a multiple of A. The required control pulses for the four transistors or thyristors of the inverter are derived by the logic circuits shown. Frequency A may be varied to vary the effective output frequency of the inverter; B may be varied to vary the pulse width and hence the effective output voltage. Three such control circuits may be used controlling three separate inverters so as to provide pulses (Fig. 7, not shown) for a three-phase system. Figs. 9 and 11 (not shown) depict alternative logic systems. Fig. 14 (not shown) depicts a circuit for the pulse sources A, B each comprising a unijunction transistor relaxation oscillator, every nth pulse of the high frequency oscillator being locked by the output of the lower frequency oscillator.
